TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented. July 25, 1905.

Application filed October 18, 1904. Serial No. 228,992.

To (oZZ whmn it NLMy 0072007 71,.-

Beit known that I, EDWIN E. BARNEY, acitizen of the United States, and aresident of Syracuse, in the county of Onondaga and State of New York,have invented certain new and useful Improvements in Type-l/VritingMachines, of which the following is a specification.

This invention relates to type-writing machines, and has for its mainobjects to provide an improved construction of type-bar-hanger supportand an improved construction of washer or the type-bar hanger.

One embodiment of my invention is illustrated in the accompanyingdrawings, where- 1n Figure 1 is a front elevation of a type-barsegmental support, showing several type-bar hangers in position thereonand portions of the type-bars mounted in said hangers. Fig. 2 is asectional side elevation taken on the line :1 n of Fig. 1 and showingthe type-barsmounted in the hangers. Fig. 3 is a fragmentary bottom planview of the segmental support, showing the left-hand side thereof. adetached view of one of the type-bar-hanger washers and showing the sameas it appears in front elevation when mounted in the machine. Fig. 5 isa similar view of another construction of washer.

I have shown my invention as applied to a vertically-disposed opensegment of the style employed in the Monarch type-writing machine; butit is to be understood that the invention as a whole or in part may beapplied to type-writing machines having different constructions ofsupporting means for the typebars.

In the drawings, 1 is the type-bar segment, or support, the front facewhereof is formed with concentric steps 2 and 3, the step 2 being backof and higher than the step 3. The front vertical face of step 2 isformed with a shallow grooved, and the corresponding face of step 3 isformed with a similar groove 5, the grooves 4 and 5 being struck fromthe same center as the top and bottom of the segment. On the front faceof the forward step 3 a series of type-bar hangers is mounted, only oneof such hangers 6 being shown. Each hanger 6 is secured in position by aheaded screw 7, which screws into a tapped hole 8 in the segment at thebottom of the groove 5, the centers of the series of holes 8 being on anarc struck from the same center Fig. 4 is as groove 5. A series ofshallower or narrower and shorter hangers is secured behind the firstseries of hangers against the front vertical face of the rear step 2.The reference-numeral 9 designates one of the hangers of this rearseries, and this hanger is secured in position by a headed screw 10,which screws into one of a series of tapped holes 11, formed in thesegment at the bottom of the groove 4, the series of holes conforming tothe curve of the groove. The arrangement of the two se' ries of hangersis similar to that disclosed in the pending application of Henry W.Merritt.

Interposed between the head of the screw 7 and the hanger 6 is a washer12, which is provided at its top with a lug 13, formed at substantiallyrightangles to the longitudinal axis and at the bottom with a shortdepending tongue or lug 14. The lug 13 is formed with two perforations13*.

Secured against the bottom face of the segment 1 is a strip or band ofmetal 15, which is held in place by a number of headed screws 16, whichscrew into the under side of the segment. The forward edge of the strip15, which is in substantially the same vertical plane as the lower endsof the washers 12, is formed with a series of shallow notches 17, sopositioned as to receive the depending lug 14: of each washer 12.

Each of the hangers 9 is provided with a washer 18, the bottom' edge ofwhich conforms substantially to and is in contact with the top of theforward step 3. The washers 18 are substantially D-shaped in plan andeach is arranged so that a portion on each side of the center line is incontact with the top of the step 3. The washers are thus prevented fromturning or becoming disarranged.

Pivotally mounted in each hanger 6 is a type-bar 19, carrying at itsfree end a typeblock 20, provided with two types, said typebar beingconnected by a link 21 with the type-actuating mechanism, which is ofwellknown construction and which it is not deemed necessary to show ordescribe herein. Each of the rear hangers 9 pivotally supports atype-bar 22, which is formed with a gooseneck near its pivot, so as toenable it to clear the hangers of the front series, said bar 22 beingactuated similarly to the type-bar 19. Attached to each type-bar is arestoring-spring 23, the rear end of which is hooked into one of theholes 13 in the lug 13 of a front washer 12, each lug 13 serving tosecure the restoring-spring of the type-bar pivoted in its associatedhanger, as well as the spring of the type-bar pivoted in one of thehangers of the rear series, which is behind its associated hanger.

As heretofore constructed the face or faces of the segment against whichthe hangers have been mounted have been substantially in one plane, sothat in screwing down each securing-screw in order to fix the hangerfirmly in place that portion of the under surface of the hanger which isnearest the screw is pressed most forcibly against the surface of thesegment. This is so because the contacting surfaces of the segment andhanger, though finished as smoothly as is possible in the practicablework of manufacture, are found not to be perfectly smooth and are unevenor formed with minute depressions and elevations. It is thereforeimpossible to obtain an absolutely perfect contact throughout of thehanger with the segment in the ordinary construction, since those partsof the contacting surfaces near the securing-screw will be pressedtogether more firmly and closely than the outer portions of thecontacting surfaces, or, in other words, those portions farthest removedfrom the securing-screw. The consequence is that the hanger even afterit has been screwed down as tightly as possible may be turned about thesecuring-screw and so disarranged as to throw its type-bar out ofalinement. One of the objects of my invention is to remedy this defect.The surface of the segment being depressed or cut away in theneighborhood of the securing-screw, the surfaces of the segment andhangers are thereby caused to contact at a greater distance from thesecuring-screw than in the old construction and in four lines ofcontact, thus giving a greater leverage to the frictional contact, andconsequently making it much more difficult to rotate or disarrange thehanger after it has once been secured in position.

As the securing-screws are tightened in order to fix the hangers firmlyin place there is a tendency on the part of the washers as formerlyconstructed to turn with the screw, and they are thereby caused tointerfere with their neighbors, and sometimes in the case of the forwardwashers this turning or displacement causes the restoring-springs 23 tointerfere with each other. hen my invention is employed, it isimpossible for this displacement of the washers to occur, since eachforward washer is held immovably in position by the engagement of itslug 14 with the notched positioning member 15, while each rear washer isheld immovable by the contact of its bottom edge with the top of thefront face of the segment, which serves as a positioning member for therear washers. Furthermore, the washers serve the purpose of distributingthe pressure of the securingscrews along the lines of the top edges ofthe hangers and more widely than when the screws alone are used.

Various changes of construction and arrangements of parts may be madewithout departing from the gist of my invention, and parts of it may beused without other parts.

hat I claim as new, and desire to secure by Letters Patent, is
